ADC3682IRSBT

Analog To Digital Converters (ADC) Overview

The ADC3682IRSBT is a dual-channel, 18-bit analog-to-digital converter (ADC) from the Texas Instruments ADC368x family. It operates at a sampling rate of 25 MSPS with a serial LVDS interface and differential inputs. The device features a noise spectral density of -156.1 dBFS/Hz and an SNR of 84.7 dBFS at 1.1 MHz input frequency. Power consumption is typically 119 mW per channel at 25 MSPS using an external reference. It supports an industrial temperature range from -40°C to +105°C and is housed in a 40-pin VQFN package measuring 5 mm x 5 mm.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to ensure correct packaging and tape-and-reel specifications. Confirm that the component meets RoHS compliance requirements for your target region. Cross-reference the datasheet revision history to validate any recent design changes or updates to the electrical characteristics before finalizing procurement plans.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC3682IRSBT when a balance between high resolution and moderate speed is required. Compare its 25 MSPS rate against the ADC3681 (10 MSPS) and ADC3683 (65 MSPS) to match system bandwidth needs. Ensure the design accommodates the 1.8V supply voltage and utilizes the appropriate SLVDS interface configuration to minimize digital interconnects while maintaining signal integrity.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC368x series, which includes pin-compatible variants with different speed grades. The family shares a common 40-pin QFN footprint and core architecture, allowing for flexible design upgrades. The ADC3682 specifically targets applications requiring 25 MSPS throughput while maintaining the low-noise and ultra-low-power characteristics defined by the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC3681IRSBR and ADC3683IRSBR are pin-to-pin compatible alternatives within the same family. Consider the ADC3681 for lower power consumption at reduced speeds or the ADC3683 for higher bandwidth requirements. Verify that the specific ordering suffix matches the desired packaging format.
